Ocular injury: Prevalence in different rural population of Bangladesh
This population based cross-sectional study was conducted on 8283 persons of all ages in five districts, selected conveniently, to assess the magnitude of ocular injuries, their causes and consequences in rural Bangladesh. Six Upazilas from five districts and from each Upazila one Union was selected randomly. One village, the ultimate cluster, was then selected conveniently from each Union. All people (n = 8283) in the 8 villages were then surveyed. Out of 8283 population (ranging from 1-120 years) surveyed, 167(2%) had history and/or evidence of past ocular trauma with a yearly incidence of 6.2 per 1000 per year. Study demonstrated a female predominance with male to female ratio being roughly 4:5. Majority (82%) had at least one episode of trauma in their life-time with mean age at 1st trauma being 20 years. Nearly 40% of the traumas were caused by blunt objects followed by penetrating object (22.3%) and sharp instrument (18.1%) with home being the primary place of occurrence (55.1%). Evidence of ocular trauma was found on eye-lid (15%), conjunctiva (11.4%) and cornea (10.2%) as scars. The older participants (? 30 years), females, illiterates, agriculture labors, housewives and household workers were more likely to receive trauma. Majority (86.8%) of the subjects received treatment following injury. The median time lapsed between injuries and receiving first treatment was 5 days and that between injury and visiting an eye-specialist was 18 days. Selftreatment and treatment from over-the-counter comprised 45% and 42.1% respectively followed by eye-specialists (25.5%), village quack (22.8%), graduate doctors (19.3%) and traditional healers (6.9%). About 87% received conservative management, with 12.4% needing hospitalization. Most of the injured (92.8%) and non-injured (95.2%) eyes had normal vision before trauma as informed by the respondents. Following trauma, 18% had impaired, 10.7% severely impaired vision and about 6% were blind. Job abstinence due to trauma was 53% with median wage loss being10 days. The study concludes that point-prevalence of ocular trauma in rural area is around 2% with blunt objects commonly causing the trauma and one in every 16 trauma-hit case undergo blind. Addressing blindness from ocular trauma, should, therefore, be a priority for eye care programs in rural Bangladesh.
